RAILWAY-TRACK CONSTRUCTION.

Speciiication otLettei-s Patent.

Patented Aug. 9, 1910.

Application iled March 29, 190B. Serial No. 488,494.

To all whom 'it may concern:

Be it known that I, ABRAHAM L. BUSH, a citizen of the United States, residing at East Oranue, in the county of Essex and State of New ersey, have invented a new and useful Improvement in Railwaylrack Construc- "ons, of which the following is a specification.

This invention relates to that Aclass of rail- Away track constructions in which the track rails are supported on 'short Wooden blocks which rest upon a bed or foundation of concrete, and particularly to a construction of this general character in which the supporting block is secured iu a recess in the concrete bed by means of a removable filling piece or wedge. which is inserted between one side of the block and the adjacent wall of the recess, as represented in Patent No. 905,645, granted to me December l, 1908.

` The main object of the resent invention is to provide simple and e cient means for holding the supporting block and the filling piece or wedge securely and removably in position in the recess of the concrete foundation whether a guard rail is used in the structure or not, as in subways and tunnels where the cai-sare generally electrically 0perated and a lighter equipment is used.

In the accompanying drawings: Figure 1 is a. transverse vertical section of this improved track construction. Fig. 2 is a top lan View of the same. Fig. 3 is a vertical ongitudinal section in line 3 3, Fig. 2, on an enlarged scale. Fig. 4 is a vertical trans verse section in line 4-l, Fig. 2, on an eularged scale.

Like reference characters refer to like parts in the several figures.

A represents a tunnel tube or other sup port for the concrete bed or foundation B.

C represents the horizontal open-ended recesses formed. transversely in the concrete bed, D the wooden supporting blocks arranged in the recesses and provided at one side with an inwardly or rearwardly facing shoulder 10 with which an outwardly or forwardly facing shoulder 11 on the adjacent side of the bed engages, E the filling piece or wedge which is inserted between the n J- positc side of the block and the adjacent sit c of the recess, and F the track rails. All of these parts may be constructed and arranged as described in said patent or in any other suitable manner.

G represents a tie plate which is arranged beneath the rail and upon the supporting block and tillino piece or wedge and which supports the rai on the block. This plate is secured to the block by any suitable means, preferably, by lag screws 12 which pass through caps or head pieces 13 bearing u pon the base of the rail. The tie plate 1s connected with the wedge or filling piece E by a lag screw 14 or other suitable removable fastening means, whereby the wedge is held securely in position after it has been driven home.

The tie plate forms a. seat for the rail and distributes the load applied to the rail over a considerable portion of the Wooden supporting block and also over a port-ion of the filling block or wedge, and these wooden parts are thereby utilized advantageously in supporting the rail.

In driving the filling block or wedge home its tendency is to rise and this tendency also manifests itself under the hammering and jarrnv caused by the traffic passing over the rail. 4ising of the filling block or wedge is prevented by the tie late which extends over this block and the ag screw connecting the tie plate with the filling block prevents movement of the latter lengthwise of the recess or transversely to the rail under traffic. Upon withdrawing this lag screw and the lag screws securing the plate to the support ing block, the wedge can be withdrawn and the supporting block removed from the recess wlthout raising the rail or disturbn any of the adjacent blocks. Trailic need therefore not be interfered with if a block regluires to be renewed.

he supporting blocks are preferably further secured to the concrete bed by removable anchor bolts 15 which pass down throu h the blocks into screw nuts 16 embedded 1n the concrete foundation below the recesses in which the blocks are arranged. Upright tubes 17 of tin or other suitable material extend referably from the bottom of the recess own to the screw nuts to kee the space for the insertion of the anchor lts open, and prevent the concrete from setting in contact with the anchor bolts. These bolts hold the supporting blocks down against any tendency to move up and down under the varying pressure and wave motion of the rail as the load passes over the latter, while the wed e or filling lpiece engaging against the si e of the bloc: and pressing the opposite shouldered side of the latter lindernea block and holdin lc'essbqlde the bloekpugninst longitudinal end nideneviseincivellltntl in the recess.

I olnimas my invention z 1. In a railway track construction, the combination with n concrete bed having n recess which is open nt one end, n reibsu ortng block arranged in said recess, a fi l -mg block inserted betwecnone side of said supporting block and the 'adjacent side wnll Of'Said recess, and n rnll resting upon sold supportin block, of e tie plate arranged the rail and upon said sup orting block und extending over said fi ing the latter in place, substantially as set Orth.

2. In n railway track construction, the combination with n concrete bed having a recess which is open nt one end, n rail-su porting block arranged in said recess, a ling block inserted between one side of said supporting block und the adjacent side wall of said recess, and n ruil resting upon said supporting block, of n tie plate arranged undel-neath vthe rail and upon said supporting block und extending over said filling block and holding the letter in place,`means for securing said tie plate to said supporting block, and means for securing said filling block to said tie plate, substantially as set forth.

3. In a railway track construction, the combination with n concrete bed having n recess which is open nt one end, a rail-supporting block arran ed in said recess, contiguous sides of sai recess und block being provided with interlocking shoulders, n fill 1n `block arranged between the opposite si e of said sup orting block und the adjacent side wall o said recess, and n rail resting upon said su porting block, of aA tie plate arranged un erneath the mil and upon said supporting block and extending over said Iillmg block and holding the letter in place, menus for securing said tie plate to said supporting block, and means for securing said filling block to said tie plate, substantially as set forth.

Witness my hand in the presence of two subscribing witnesses.
